What is a Liter per Hour (l/h)?

A Liter per hour (l/h) is a metric unit used to measure volume flow rate.

It describes how many liters of a fluid pass a specific point in one hour.

It is part of the metric system and is a straightforward way to measure a slow, sustained flow. You will most commonly see l/h used to describe the flow rate for:

Aquarium filters
Drip irrigation systems
Medical intravenous (IV) drips
Small pumps and fountains
Laboratory dosing pumps

Why Use Liters per Hour? (The Practical Example)

The Liter per hour unit is ideal for measuring low-flow or "trickle" systems where precision is essential.

Using a larger unit like liters per second (l/s) for these applications would result in a very small, impractical decimal. For example, a slow chemical drip might be:

0.005 l/s (hard to read and monitor)
18 l/h (a simple, whole number that is easy to manage)

By using l/h, the rate is expressed as a more manageable number, making it easier to monitor, control, and document for both home and industrial use.

Liters per Hour in the Metric System

As a unit within the metric system, l/h is derived directly from the standard units for volume (liter) and time (hour).

This makes it an intuitive measurement for anyone familiar with metric units.

Its simple relationship with other metric measurements (like cubic meters per hour) simplifies calculations, especially when compared to imperial units like gallons per hour (GPH).

Common l/h Conversions

A key part of understanding l/h is knowing how it relates to other common flow rates.
